Specification£º
GCK Low-voltage withdrawable switchgear is a complete switchgear assembled with modules in factory.They are divided into power center switchgear(PC),motor control center swithgear(MCC) and power factor autocompenstaing switchgear.It meets the requirments of IEC60439 ¡¶Low-voltage complete switch equipment and controller¡·GB7251.1 ¡¶Low-voltage complete switch equipment and controller¡·standard.
Product feature£º
The switchgear is of a combination structure.The cubicle consists of coumns,crossbars,special pyramdal joints,connecting parts,doors and various mounting plates,which are punched with steel sheets by means of a special techno-logy and fixed each other by screws.This kind of structure prevents the deformation and stress caused by welding.The overall dimensions for the cubicle and its components and all the opening dimensions are in terms of M of 20mm.(M refers to "module").The components have a high generality and adaptability and the whole cubicle has enough michanical strength.The cubicle is divided into three parts:busbar compartment,cable compartment and assembly compartment.
GCL:The busbar compartment and cable compartment are in the rear part of the cubicle,in the middle of which are mounted horizontal busbars and on the bottom are fixed N line and PE line through high-strength insulating clips.The coulets have their busbars withdrawn for the convenience of cable connection.The assembly compartment is in the front of the cubicle.
